Gear

Neugear・Hartevelt (ノイギア・ハティヴェルト Noigia・Hativeruto), more commonly known as Gear (ギア Gia), is a werewolf with a connection to Kuro's past.

Appearance
Gear has chin-length black hair, white eyelashes and gold eyes. He's relatively short and has so far only been seen wearing a white suit, black dress shirt and white tie with black shoes along with a long gold earring in his right ear. He usually doesn't wear the suit jacket, opting to carry it instead, but also has an additional furry black coat.

When using his werewolf powers his skin is covered by thick black fur and he sprouts a pair of black ears along with a long fluffy tail. Whenever he activates his powers he rips his clothes and has to shed the fur he grows, much to the chagrin of Youtarou.
